Very helpful post. It's given me a few things to test. I am working on a Philco 50-T1404 and had no HV (i've only tested tubes including crt and replaced the electrolytics). I pulled out my Sel-Sun test pic tube/yoke (removed the existing yoke plug which also disconnects the focus coil) and voila - had HV and a raster on the test tube. I'll ring out the focus coil and deflection coils directly tonight and see what I come up with. I'll also check my HOT cathode current.
